I'm a member and this is just saying "it costs $.79 / mo" but you pay in one payment.

There's no auto-renewal, you get an email telling you your membership is expiring and asks you to pay again.

What you've posted implies they're lying and they are verifiably not.

No idea why you get downvoted... on one hand, a site like this one needs some revenue in order to keep up their work, I think we can all agree on that one. But unclear messaging about how much exactly you will be paying is not going to encourage anyone to sign up...

Niche website with extremely thorough and exacting analysis, that provides most of its data completely for free has a modest payment model. I'm shocked, but because of how strikingly reasonable it is.

How do you pay a single one-time payment at a per month rate? How many months do they charge for the one-time payment?

Usually a 'single one-time payment' would be a payment for life. Typically for apps they're What you appear to be describing would be a pre- payment plan at 80¢/mo.

I think it's interesting to have observed the changes over the years. Before it was about having as thin tires as possible, pumped as hard as possible. Then one realized that only gives a low rolling resistance on perfectly even surface, something softer can absorb more of the little bumps (and also perhaps not fatigue the rider as much from a bumpy ride). Then bytul vs latex vs tpu tubes. Or go entirely tubeless is in vogue lately, often with wider tires and less air in them.

There are other trade offs than rolling resistance. Like puncture resistance, grip/cornering ability, aerodynamics, weight etc. that also comes into account when choosing a tire setup.

The rolling resistance data is interesting, but it would be nice to see some more realistic testing. For example ramping the pressure up on a smooth surface gives lower rolling resistance on a rolling road. But in the real world super high pressures cause the whole bike and your body to shudder and vibrate, which also consumes energy. So there is a sweet spot, between heating the tyre up too much, and passing too much vibration through.
